Crews have been working around the clock in Oroville to protect the Oroville Dam’s emergency spillway ahead of the storms looming the next several days. About 125 construction crews are out placing 1,200 tons of material on the spillway per hour to try and stop erosion.

Officials are continuing to release water from the reservoir as well, with the lake levels falling an additional 8 feet as of Thursday morning. Lake Oroville is now about 29 feet below the emergency spillway.

Chains are up on I-80 from Kingvale to Donner Lake with snow on the roadway. Please drive carefully this morning over the pass! #cawxpic.twitter.com/7WAtfT0Ig5

Interstate 80 is open but chain controls are in effect from Kingvale to the Donner Lake Interchange. A series of mudslides continues to be an issue for Caltrans crews, with the freeway seeing another closure on Wednesday.
